Well you are 6/8 hq staff so what is the problem exactly? You left arguably the least useful staffs till the end to hq although imo Neptunes, Terras and Vulcans are below Aquilos, Jupiters, plutos and Austers in no particular order, with Apollos right bottom. You havent stated weather you are in need of gil or something and need so sacrifice a hq staff. If not i fail to see any reason to go back to nq on any staff.
Btw my perferred order is from the perspective of someone with rdm and blm 75 not sch but it applies pretty much the same to sch. Im currently trying to get alkalurops would be sexy addition to my blm enfeeb build.
